Autotuner for Linux?

[Giorgio-10]

Hi,
i'm looking for an autotuner (to tune bad singers' voice), is there anything native for Linux?
Thanks

There's the Autotalent LADSPA plugin, but either its effects are a lot more
subtle than Autotune or I'm way better of a singer than I thought I was.

I'm gonna go with the former.

Thanks for the heads up. I recently had to "autotune" my flute playing
(using a Windows VST), so a native solution would be very useful :D

Anyway, a good way to test it would be to either play the original and
effected side by side on separate tracks, which makes even the slightest
differences immediately apparent, or do the same but invert the phase of
one to hear only the difference between the two.

Or I don't know how to use it properly.

I am sure I am in the third category and may be in the first. I am pretty sure
I am not in the second.

Does anyone have any pointers to docs to solve the issue I mention?

Nice. I just tested it, and it seems to work.

However it's cpu usage rises to > 100% when theres a pause in the audio
input. Anyone else experience this?

In autotalent.c, changing line 560:

  psAutotalent->ffttime[ti] = psAutotalent->ffttime[ti] / psAutotalent->ffttime[0];

to

  psAutotalent->ffttime[ti] = psAutotalent->ffttime[ti] / (psAutotalent->ffttime[0] + 1e-10f);

should help.

I see one problem with this plugin: its period estimation is always
an integer number of samples, and this is introduces pitch errors
by itself ! It should be relatively easy to correct.

Ciao,

unbelievable: this thing really exists ;-) I'm stunned ....

and yes - it works. I do not see any effect on the cpu-usage if it does
not get any input. Works smoothly indeed ;-)

so thanks a lot for that - I shure will not use it for what its name
stands for but there will be some more orks and zombie-aristocrats
stalking my tracks from now on ;-)

Denormals, right? However the problem still remains after applying this
fix :-(

Division by very small numbers, possibly resulting in NaN and
friends. Here the change I posted made all the difference, but
I'll look again later tonight.

Guys, I am not a coder, I can't deal with patches, I am only a (simple-minded) musician.
have you got any source code ready (with the patch mentioned above)  for download and install, possibly involving ./configure, make and (sudo) make install? A .deb file would be a more preferred solution...

Thanks in advance.

There is only one C file in the tar.gz.  It is autotalent.c.  Download
the tar.gz from http://web.mit.edu/tbaran/www/autotalent.html

then

tar -xvzf autotalent-0.1.tar.gz
cd autotalent-0.1
emacs or vi autotalent.c

change line 650 to what is listed below (in emacs you can go to line 650
by pressing Esc (don't hold), typing 650, then hitting return).

Save the file, exit the editor then

make
make install

That's it.  This assumes that your LADSPA plugins are
in /usr/lib/ladspa.  If they aren't there then they're probably
in /usr/local/lib/ladspa.  If so you need to change the Makefile to
point there - it should be intuitively obvious to the most casual
observer (math prof speak) which line needs to be changed.

Jan

PS - sorry for the top post.

yes, please...

I didn't find any more obvious errors, and here things work
perfectly. Could it be you are feeding it undesirable floats ?
You can check this with bitmeter. If you don't know this tool
(I didn't until a few minutes ago) it's on

 I am not a developer (I wish I were) but I definitely think that this
program is something that the open-source community needs, and some
further development on it would benefit us greatly.  One of the big
obstacles to people switching to ardour (from what I've heard) is no
tuning program like this.

 I think if people fine tuned the algorithm as you seem to be doing,
here, and improved the interface, we'd really be on to something
wonderful.

I might investigate further over the weekend, I have the flu atm so...

I'm in renoise btw, so I cannot just plug bitmeter in, I could route
audio from the track in question to bitmeter, I guess.
